Dornfeld University of California Berkeley CA USA Introduction New demands are being placed on monitoring systems in the manufacturing environment because of recent developments and trends in machining technology and machine tool design high-speed machining and hard turning for example . Numerous different sensor types are available for monitoring aspects of the manufacturing and machining environments. The most common sensors in the industrial machining environment are force power and acoustic emission AE sensors. This section first reviews the classification and description of sensor types and the particular requirements of sensing in manufacturing by way of a background and then the state of sensor technology in general. The section finishes with some insight into the future trends in sensing technology especially semiconductor-based sensors. Principles of Sensors in Manufacturing 7 In-process sensors constitute a significant technology helping manufacturers to meet the challenges inherent in manufacturing a new generation of precision components. In-process sensors play .
